Product description2

2 Product description

FM456 and FM457 function modules (accessories)

With these KSE modules (cascade modules) it is possible to control multiple wall-mounted or floorstanding boilers with EMS/UBA 3 (FM456: up to 2 boilers, FM457: up to 4 boilers). The wall-mounted boilers can have different outputs.

Up to 2 function modules can be used in a single control panel ( Tab. 1, page 4). This way, a maximum of 8 boilers can be operated (for information about the ECOCAN-BUS networking of control panels with FM456/457, see the service instructions of the corresponding control panel. See especially the chapter about "Modules and their functions").

Additional module functions are:

The FM456 and FM457 include a heating zone without mixing valve. You cannot connect a remote control unit for this heating zone. The pump for this heating zone is using the 120 V pump output.

Via the 0 – 10 V input, external set point control (temperature or output) is possible ( Fig 2, page 10).

USER NOTE

To avoid generating undefined input values, never apply voltages greater than 10 V to the 0 – 10 V input.

USER NOTE

You can adapt the curve if desired ( Chapter 5.2).

If you select the "utlz.leftovr.ht" function, you can also utilize the residual boiler heat for heating the storage tank.

"Leftover heat use yes"

If you select "utlz.leftovr.ht yes", the control panel calculates the shutdown temperature of the burner and the runtime of the primary pump via the leftover boiler heat, until the cylinder is fully heated. The burner is switched off before the set DHW temperature is reached. The tank heating pump continues to operate. The control panel calculates the runtime of the primary pump (between 3 and 30 minutes) to heat the storage tank.

"Leftover heat use no"

If you select "utlz.leftovr.ht no", you will only use a small amount of leftover heat. The burner runs until the desired DHW temperature has been reached. The storage tank primary pump runs on for 3 minutes after the burner has been switched off.

If you select the "thermal disinfection" function, the DHW is brought to a temperature (158 °F (70 °C)) once or several times a week. This is high enough to kill off germs (e.g. legionella bacteria).

The tank primary pump and DHW recirculation pump run constantly during the thermal disinfection process.

If you have selected "thermal disinfection yes", thermal disinfection starts according to factory settings or your own preferences.

Thermal disinfection is indicated by the LED on the FM441 module.

You can adjust the factory settings for thermal disinfection via additional menus.

The system tries to reach the set thermal disinfection temperature for three hours. If this fails, the error message "thermal disinfection failed" appears.

7.12 Setting the recirculation pump intervals

Interval operation reduces the operating costs of the recirculation pump.

You can set DHW to be immediately available at the draw-off points via the "recirculation per hour" function.

The set interval applies during that time in which the time program enables the DHW circulation pump. This may be:

– the factory-set recirculation pump program

– your own recirculation pump program

– a connection to the heating zone switching times

In constant mode the recirculation pump operates continuously when in day mode, and is switched off in night mode.

Example:

A time program was input, which during the period from

5:30 am – 10:00 pm (05:30 h – 22:00 h) switches the recirculation pump on with the setting "recirculation per hour 2 cycles".

The circulation pump is switched on
